# Use errors.Is in annotateLeaseFailure passthrough test

errorlint flagged the `!= err` comparison on a wrapped error. The
helper currently returns the input untouched on the non-lease branch
(so `==` works), but the contract is "pass through unchanged" — switch
to errors.Is so the test still passes if the helper ever wraps with a
non-lease annotation.
